Lyrics
戦場から戻ってこない 伸るか反るか 生きていても死んでも 永遠の誓い Alea iacta est​
 * -|Romaji=

残念ながら 人生で いくつかミスを作った でも 没法子 玉の汗だった（押し進める） 君（ためらいがちな） 優しい言葉が 脈打つを聞こえる

君が恐れることはわかり （パンッ！）不安を受けいれる（パンッ！）利点として使用 隠された勇気を伝える

戦場から戻ってこない 突っ掛かるや気が利く 風の方向に行く限り 恐れることはない 虎穴に入らずんば 虎子を得ず 頑張ろう 伸るか反るか 覚えておいて Alea iacta est​！

結果を心配無用 誇りで戦い続ける 拳を高くあげる 僕たちは戦争の勝者というを打ち明ける

きっと（傷がつくよ） 傷に包帯を貼って 前に進む もうすぐ 痛みを耐えるのに十分な強くなる

故障して泣く時間がない 戦闘で自分を表現ください そうする限り 勝利だろう それなら泣くできる 放胆すぎると いうことはない 恐怖は不明と見なされ 不合理にするほどに 恐ろしい

大きなチェス盤として戦場を想像してみて 正確には 粗いな攻撃 打ち勝つ

戦場から戻ってこない 伸るか反るか 生きていても死んでも 風の方向に行く限り 恐れることはない 虎穴に入らずんば 虎子を得ず 頑張ろう 伸るか反るか 覚えておいて Alea iacta est​！

永遠の誓い Alea iacta est​ There's no going back from the battlefield It's a win or lose, whether you live or die A vow for eternity, Alea iacta est​!

I've made some mistakes in my life I regret But nothing can be done Beaded with perspiration, (Gotta push through) you, who's tending to hesitate, hear my gentle words beating for you

It's understandable for you to be afraid (Pang!) Embrace your fears (Pang!) Use it as an advantage Convey that hidden bravery

There's no going back from the battlefield It's okay to charge in or think about the next move As long as you go in the direction of the wind, then there's nothing to fear You can't do anything without risking something Just do your best, whether you win or lose Remember, Alea iacta est​!

Don't worry about the results Continue to fight with pride Raise your fist high up into the air Declare that we're the winner of this war

Surely (you'll get hurt) Apply a bandage and get moving Soon, you'll be strong enough to withstand the pain

There's no time to breakdown and cry Express yourself in combat As long as you do so, we'll be victorious Then you can cry There's no such thing as fearlessness Fear are considered the unknown Terrifying enough to make us irrational

Imagine the battleground as a big chessboard Be precise, attack roughly Conquer

There's no going back from the battlefield It's a win or lose, whether you live or die As long as you go in the direction of the wind, then there's nothing to fear You can't do anything without risking something Just do your best, whether you win or lose Remember, Alea iacta est​!

A vow for eternity, Alea iacta est​!
